Quiz: New Horizons for Geothermal Energy

Geothermal energy comes straight from the Earth. The radioactive decay of atoms in the core generates heat, and by the time that heat reaches the surface, it is measured to be about 0.1 watts per square meter, or about 10,000 times less than the heat flux from the sun. But in certain places, that heat is enough to turn into electric power. Test your knowledge of geothermal energy in this ASME quiz.
